There is a new mission today on Dizzywood called Ghostly Pumpkin. U need to have the ghost ray power to do it so go get it if you don’t. U can get ghost ray from the ghost guy in Tanglevine Jungle.
Anyway the pumpkin is hidden behind one of the pillar things in Presto’s Edge. It is on the other side of the chasm so cross the bridge and you will get to a spot with lots of pillars with runes on them. The pumpkin is hidden behind one of those. Sorry I don’t have a picture but you can see it here.
